DETAILED DESCRIPTION

The embodiments of the invention will now be described with reference tothe accompanying drawings, wherein similar numbers in the drawingsrepresent similar elements. A buckle 100 provided by the invention has acontrol circuit and is mainly used for actuating or disconnecting thecontrol circuit disposed on a baby carriage, but is not so limited. Thebuckle 100 may also be used for actuating or disconnecting a controlcircuit of any equipment with a buckle.

As shown in FIGS. 1 to 20, the buckle 100 of the invention includes amale buckle 110, a female buckle 120, and an actuating structure 130disposed between the male buckle 110 and the female buckle 120. When themale buckle 110 and the female buckle 120 are engaged, the actuatingstructure 130 generates an actuating signal. When the male buckle 110and the female buckle 120 are disengaged, the actuating structure 130generates a disconnecting signal. The control circuit may beautomatically actuated or disconnected according to the actuating signalor the disconnecting signal. The control circuit may also control otherelectronic components according to the actuating signal or thedisconnecting signal.

In the invention, the control circuit may be disposed inside or outsidethe buckle 100. When the control circuit is actuated, the controlcircuit may control other electronic components to work.

As shown in FIGS. 1 to 20, in the buckle 100 of the invention, theactuating structure 130 includes a first conductive member 131 and asecond conductive member 132. The first conductive member 131 and thesecond conductive member 132 are disposed on the male buckle 110 and/orthe female buckle 120. One of the first conductive member 131 and thesecond conductive member 132 is electrically connected to the controlcircuit. The male buckle 110 and the female buckle 120 are engaged ordisengaged, such that the first conductive member 131 and the secondconductive member 132 are in contact or disconnected to generate theactuating signal or the disconnecting signal. In the following,different embodiments of the buckle 100 of the invention are describedwith reference to the accompanying drawings, respectively.

As shown in FIGS. 1 and 2, in the first embodiment of the buckle 100 ofthe invention, one of the first conductive member 131 and the secondconductive member 132 is disposed on the male buckle 110 and another oneof the first conductive member 131 and the second conductive member 132is disposed on the female buckle 120. When the male buckle 110 and thefemale buckle 120 are engaged, the first conductive member 131 and thesecond conductive member 132 are in contact. When the male buckle 110and the female buckle 120 are disengaged, the first conductive member131 and the second conductive member 132 are disconnected.

More specifically, the first conductive member 131 is fixed on the malebuckle 110 or integrally formed with the male buckle 110. The secondconductive member 132 is disposed on the female buckle 120 andelectrically connected to the control circuit. The second conductivemember 132 has two contact ends 1321. When the male buckle 110 and thefemale buckle 120 are engaged, the first conductive member 131 and thetwo contact ends 1321 of the second conductive member 132 are in contactto make the control circuit conductive. When the male buckle 110 and thefemale buckle 120 are disengaged, the first conductive member 131 andthe two contact ends 1321 of the second conductive member 132 areseparated to disconnect the control circuit.

In this embodiment, the first conductive member 131 is a conductive bodydisposed on the male buckle 110. The conductive body may be formedindividually and then fixed on the male buckle 110. The conductive bodymay also be integrally formed on the male buckle 110 by insert molding.The conductive body may be disposed on a first buckle body 111 and/or asecond buckle body 112 of the male buckle 110. Furthermore, the secondconductive member 132 is two conductive wires disposed on the femalebuckle 120. The two conductive wires are electrically connected to thecontrol circuit and not conductive with each other. When the male buckle110 and the female buckle 120 are engaged, the conductive body of themale buckle 110 and the two conductive wires of the female buckle 120are in contact to make the control circuit conductive. When the malebuckle 110 is disengaged from the female buckle 120, the conductive bodyis separated from the two conductive wires to disconnect the controlcircuit.

Needless to say, the actuating structure 130 is not limited to theaforesaid arrangement. In another embodiment of the buckle 100 of theinvention, the first conductive member 131 and the second conductivemember 132 of the actuating structure 130 are disposed on the femalebuckle 120 and an automatic ejection member 140 in the female buckle 120is used to make the first conductive member 131 and the secondconductive member 132 in contact or separate, wherein the automaticejection member 140 is a device used to eject the male buckle 110 out ofthe female buckle 120.These embodiments are described in the following.

In some embodiments, the second conductive member 132 is two conductivewires disposed on the female buckle 120. The two conductive wires areelectrically connected to the control circuit and not conductive witheach other. The first conductive member 131 is a metal elastic plate ofthe automatic ejection member 140. When the male buckle 110 and thefemale buckle 120 are engaged, the male buckle 110 pushes the metalelastic plate of the automatic ejection member 140 to make the metalelastic plate and the two conductive wires in contact and then make thecontrol circuit conductive. Consequently, the control circuit isactuated. On the other hand, when the male buckle 110 is disengaged fromthe female buckle 120, the metal elastic plate of the automatic ejectionmember 140 recovers to make the metal elastic plate and the twoconductive wires separate. Consequently, the control circuit isdisconnected.

Needless to say, the structure of the automatic ejection member 140 isnot limited to the aforesaid embodiment. The automatic ejection member140 may be implemented by a combination of a metal plate and a spring.At this time, when the male buckle 110 and the female buckle 120 areengaged, the male buckle 110 pushes the metal plate and deforms thespring, such that the metal plate and the two conductive wires are incontact to make the control circuit conductive. When the male buckle 110is disengaged from the female buckle 120, the spring recovers to pushand return the metal plate, such that the metal plate and the twoconductive wires are separated to disconnect the control circuit.

In other embodiments, the first conductive member 131 is arrangedindividually and fixed on the automatic ejection member 140. When themale buckle 110 and the female buckle 120 are engaged, the male buckle110 pushes the automatic ejection member 140 to drive the firstconductive member 131 to move to make the first conductive member 131and the second conductive member 132 in contact or separate, so as tomake the control circuit conductive or disconnected.

As shown in FIGS. 3 to 5A, in the second embodiment of the buckle 100 ofthe invention, the first conductive member 131 is fixed to the automaticejection member 140 disposed in the female buckle 120. The firstconductive member 131 is a metal rod. The second conductive member 132is fixed in the female buckle 120 and electrically connected to thecontrol circuit. The second conductive member 132 is a metal bucklehaving two contact ends 1321 apart from each other. A tail end 1322 ofthe second conductive member 132 away from the two contact ends 1321 isconnected to the control circuit by a wire. When the male buckle 110 andthe female buckle 120 are engaged, the male buckle 110 pushes theautomatic ejection member 140 to drive the first conductive member 131to move to make the first conductive member 131 and the two contact ends1321 of the second conductive member 132 in contact or separate.

More specifically, the second conductive member 132 is fixed on thefemale buckle 120 and the two contact ends 1321 are close to a receivingend of the female buckle 120. The first conductive member 131 isslidably engaged in an engaging groove of the female buckle 120 andlocated between the two contact ends 1321 and the tail end 1322. Whenthe male buckle 110 is inserted into the female buckle 120, the malebuckle 110 pushes the automatic ejection member 140 to move and compressan elastic member therein. The automatic ejection member 140 drives thefirst conductive member 131 to move, such that the first conductivemember 131 is separated from the two contact ends 1321 of the secondconductive member 132 to disconnect the control circuit. On the otherhand, when the male buckle 110 is disengaged from the female buckle 120,the automatic ejection member 140 automatically returns to push thefirst conductive member 131 to move, such that the first conductivemember 131 contacts the two contact ends 1321 of the second conductivemember 132 to make the control circuit closed.

Needless to say, the first conductive member 131 and the secondconductive member 132 are not limited to the aforesaid arrangement. Therelative position between the first conductive member 131 and the secondconductive member 132 may change. For example, the first conductivemember 131 may be located between the two contact ends 1321 of thesecond conductive member 132 and the receiving end of the female buckle120. When the male buckle 110 is inserted into the female buckle 120,the male buckle 110 pushes the automatic ejection member 140 and drivesthe first conductive member 131 to move, such that the first conductivemember 131 contacts the two contact ends 1321 of the second conductivemember 132 to make the control circuit conductive. On the other hand,when the male buckle 110 is disengaged from the female buckle 120, theautomatic ejection member 140 returns and pushes the first conductivemember 131 to move, such that the first conductive member 131 isseparated from the two contact ends 1321 of the second conductive member132 to disconnect the control circuit.

It should be noted that the first conductive member 131 is not limitedto the metal rod of this embodiment and the second conductive member 132is not limited to the metal buckle of this embodiment. The firstconductive member 131 and the second conductive member 132 may bearranged by other manners. For example, in another embodiment, the firstconductive member 131 may be two metal springs 132 b connected to theautomatic ejection member 140, wherein the two metal springs 132 b maybe connected by a metal wire or formed as a one-piece structure by ametal wire. The second conductive member 132 may be two conductivepillars 132 a fixed in the female buckle 120. The two conductive pillars132 a are electrically connected to the control circuit, and a distancebetween the two conductive pillars 132 a corresponds to a distancebetween the two metal springs 132 b. Accordingly, when the male buckle110 and the female buckle 120 are engaged, the male buckle 110 pushesthe automatic ejection member 140 to make the two metal springs 132 band the two conductive pillars 132 a in contact, so as to make thecontrol circuit conductive. On the other hand, when the male buckle 110is disengaged from the female buckle 120, the automatic ejection member140 automatically ejects to separate the two metal springs 132 b and thetwo conductive pillars 132 a to disconnect the control circuit.

In the invention, by means of using the automatic ejection member 140 tomake the first conductive member 131 and the second conductive member132 in contact or separate, the actuating structure 130 may beimplemented by other structures.

As shown in FIGS. 6 to 8, in the third embodiment of the buckle 100 ofthe invention, the arrangement of the second conductive member 132 isidentical to the aforesaid second embodiment. That is to say, the secondconductive member 132 is a metal buckle having two contact ends 1321apart from each other, wherein the two contact ends 1321 are close tothe receiving end of the female buckle 120 and the tail end 1322 of thesecond conductive member 132 is connected to the control circuit by awire. However, in this embodiment, the structure of the first conductivemember 131 is different from the aforesaid second embodiment. The firstconductive member 131 of this embodiment is a switch disposed on thefemale buckle 120. The switch is disposed with respect to the twocontact ends 1321 of the second conductive member 132. The two contactends 1321 are conducted or disconnected by the switch.

As shown in FIGS. 7 and 8, the actuating structure 130 further includesa movable member 150 connected to the automatic ejection member 140 andslidably engaged in an engaging groove of the female buckle 120. Whenthe male buckle 110 and the female buckle 120 are engaged, the malebuckle 110 drives the movable member 150 to move through the automaticejection member 140, such that the movable member 150 detachably acts onthe switch to make the switch and the second conductive member 132 incontact or separate. In this embodiment, the movable member 150 islocated between the two contact ends 1321 and the tail end 1322 of thesecond conductive member 132. The switch is disposed at a positioncorresponding to the two contact ends 1321 of the second conductivemember 132 by an installation base 133. The switch is located betweenthe movable member 150 and the two contact ends 1321 of the secondconductive member 132. Accordingly, when the male buckle 110 and thefemale buckle 120 are engaged, the automatic ejection member 140 drivesthe movable member 150 to move away from the switch (as shown in FIG. 7)to disconnect the control circuit. When the male buckle 110 and thefemale buckle 120 are disengaged, the automatic ejection member 140automatically returns to push the movable member 150 to move to pressthe switch (as shown in FIG. 8), such that the switch and the twocontact ends 1321 of the second conductive member 132 are in contact andthe control circuit is closed.

As shown in FIGS. 9 and 10, in the fourth embodiment of the buckle 100of the invention, the difference between this embodiment and theaforesaid third embodiment is the relative position between the movablemember 150 and the second conductive member 132 and the installationdirection of the switch. Specifically, the movable member 150 isdisposed between the two contact ends 1321 of the second conductivemember 132 and the receiving end of the female buckle 120. The switch isdisposed at a position corresponding to the two contact ends 1321 of thesecond conductive member 132 by an installation base 133 and the switchis close to the movable member 150. Accordingly, when the male buckle110 and the female buckle 120 are engaged, the male buckle 110 pushesthe automatic ejection member 140 to drive the movable member 150 topress the switch (as shown in FIG. 9), such that the switch and the twocontact ends 1321 of the second conductive member 132 are in contact andthe control circuit is closed. When the male buckle 110 and the femalebuckle 120 are disengaged, the automatic ejection member 140 ejects todrive the movable member 150 to move away from the switch. The switchautomatically ejects to be separated from the two contact ends 1321 ofthe second conductive member 132 (as shown in FIG. 10), so as todisconnect the control circuit. Other parts that are the same as theabove embodiments will not be repeated herein.

It should be noted that the conduction and disconnection of the controlcircuit are not limited to the aforesaid structures. In otherembodiments of the buckle 100 of the invention, a sensor 160 may be usedto sense an engaging state between the male buckle 110 and the femalebuckle 120, so as to make the control circuit conductive ordisconnected.

Specifically, as shown in FIGS. 11 to 15, in the fifth embodiment of thebuckle 100 of the invention, the actuating structure 130 includes asensor 160 disposed in the female buckle 120 and electrically connectedto the control circuit. As shown in FIG. 13, the female buckle 120 has ahole 121 communicating with a slot for receiving the male buckle 110.The sensor 160 is disposed on a bottom of the female buckle 120 andcapable of sensing whether the male buckle 110 is engaged through thehole 121 (as shown in FIGS. 14 and 15). When the male buckle 110 and thefemale buckle 120 are engaged, the sensor 160 senses the male buckle110. When the male buckle 110 and the female buckle 120 are disengaged,the sensor 160 cannot sense the male buckle 110. The sensor 160 may sendout different sensing signals. The control circuit is conducted ordisconnected according to the sensing signals or the control circuitcontrols other electronic components according to different sensingsignals of the sensor 160.

As show in FIGS. 11 and 12, the sensor 160 is disposed on the bottom ofthe female buckle 120 through a circuit board 161. The circuit board 161may be connected to the control circuit by a wired or wireless manner.Accordingly, when the sensor senses the male buckle 110, the sensor 160may transmit the sensing signal to the control circuit by the wired orwireless manner, such that the control circuit actuates the electroniccomponents correspondingly. When the sensor 160 does not sense the malebuckle 110, the circuit board 161 transmits the signal to the controlcircuit by the wired or wireless manner, such that the control circuitswitches off the electronic components.

As shown in FIGS. 16 to 20, in the sixth embodiment of the buckle 100 ofthe invention, the difference between this embodiment and the aforesaidfifth embodiment is that the control circuit 200 is disposed in thefemale buckle 120, and the circuit board 161 connected to the sensor 160is disposed above and communicates with the control circuit 200 (asshown in FIGS. 19 and 20). The sensing manner and principle of thesensor 160 are the same as the aforesaid fifth embodiment and will notbe repeated herein.

Furthermore, another difference in this embodiment is that the controlcircuit 200 further includes a Bluetooth module, wherein the Bluetoothmodule is used to connect an external alarm device (e.g. mobile phone,tablet computer, etc.) by Bluetooth communication. When the sensor 160senses that the male buckle 110 and the female buckle 120 are engaged ordisengaged, the control circuit 200 actuates the Bluetooth module andtransmits a signal to the alarm device through the Bluetooth module,wherein the signal indicates that the male buckle 110 is engaged ordisengaged. When the alarm device does not receive a Bluetooth signal,the alarm device sends out an alarm.

It should be noted that for the buckle 100 of the invention, when thecontrol circuit is disposed outside a buckle, the Bluetooth module mayalso be disposed on the control circuit to connect the alarm device byBluetooth communication.

The control circuit of the invention includes a communication moduleconfigured to communicate with an external mobile device. Thecommunication module instantly sends the current state of the buckle(engaged or disengaged) to the mobile device, such that a user caninstantly know the current state of the buckle. Specifically, the mobiledevice may be a mobile phone, a tablet computer, an in-vehicle device, asmart TV, a magnetic button, a smart key and other electronic deviceswith sound and/or light and/or display functions. For example, themobile device may show the current state of the buckle by differentsounds, the mobile device may show the current state of the buckle bydifferent lights, or the mobile device may show the current state of thebuckle by different images, symbols, or text. Needless to say, themobile device may also show the current state of the buckle by at leastone of sound, light, and display functions.

As mentioned in the above, the buckle 100 of the invention has theactuating structure 130 disposed between the male buckle 110 and thefemale buckle 120. When the male buckle 110 and the female buckle 120are engaged, the actuating structure 130 generates the actuating signal.When the male buckle 110 and the female buckle 120 are disengaged, theactuating structure 130 generates the disconnecting signal. The controlcircuit operates according to the actuating signal or the disconnectingsignal, such that the control circuit can be actuated conveniently andthe structure of the buckle is simple.

The structure and engaging manner of the male buckle 110 and the femalebuckle 120 involved in the buckle 100 of the invention are well known inthe art, so the explanation will not be depicted herein.
